    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. There is disclosed a method, for a second base station in a network comprising a User Equipment (UE), a first base station, and the second base station. The method is for performing Random Access Channel (RACH)-less handover of the UE from the first base station to the second base station. The method comprises: obtaining a Conditional Handover (CHO) configuration (e.g., execution condition); determining a RACH-less Uplink (UL) grant configuration; transmitting, to the first base station, the RACH-less UL grant (e.g., in a HANDOVER REQUEST ACK message); and monitoring for UL RACH-less transmissions from the UE (e.g., a RRCConnectionReconfigurationComplete message) or scheduling Physical Downlink Control Channel (PDCCH) assignments to the UE, based on the CHO configuration.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a UE in a wireless communication system using satellite access is provided. The method includes identifying whether an NAS procedure is completable before a start of a DC; and in case that the NAS procedure is completable before the start of the DC, initiating the NAS procedure by transmitting a request message to a network entity. And a method for a UE in a communications network using a satellite to access the network comprises verifying if a communication process between the UE and the network via the satellite can be completed before a start of an unavailability period of the satellite or cannot be completed before a start of an unavailability period of the satellite. The UE may only initiate the communication process when it verifies that there is enough time for the communication process to be completed the start of the unavailability period of the satellite. The communication process between the UE and the satellite may comprise an NAS procedure. The UE may only trigger the NAS procedure when it verifies that there is enough time for the procedure to be completed before the start of the unavailability period of the satellite and loss of satellite coverage for the UE. The UE may trigger the NAS procedure during a time range for which the procedure can be completed before the start of the unavailability period of the satellite and loss of satellite coverage for the UE. The NAS procedure may be any of a registration procedure, a mobility registration update procedure, an NAS request procedure, an attach procedure, a tracking area update procedure, a service request procedure, an NAS mobility management procedure, an NAS session management procedure, NAS signaling, an NAS message, any similar message that is used in EPS (or in S1 mode).

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of managing an energy performance policy, EPP, for a user equipment, UE, over a network interface of a network, for example a New Radio, NR, network such as a 5G NR network, the method comprising: sending, by the Core Network, CN, for example the Access and Mobility Management Function, AMF, thereof, assistance information on the EPP for the UE to an NG-RAN node and/or to the UE using signalling and/or messages; and managing the EPP for the UE.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for handling a slice based cell reselection in a wireless network (1000) by a UE (100). The method includes evaluating a cell reselection criteria based on a relative reselection priority between frequencies derived using a slice priority of at least one slice group supported on a frequency. The at least one slice group comprises a highest priority slice group supported by the frequency as an input. Further, the method includes determining a change in the relative reselection priority upon detecting that a best cell or a highest ranked cell in the frequency does not support the at least one slice group associated with a highest priority. Further, the method includes re-evaluating the cell reselection criteria based on the determined changed in the relative reselection priority.

    Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a network entity in a wireless communications network is provided. The method includes obtaining energy information associated with the wireless communications network and determining, based on the energy information, at least one of a quality of service (QoS) profile associated with a QoS flow of the wireless communications network and a QoS profile associated with a user equipment (UE).
